Definitions
- This invention relates generally to a fender assembly and a method for manufacturing the same.
- this invention relates to a fender assembly which may be used for protecting vehicle loading docks against damage during the loading or unloading of trailers.
- the fender assembly according to the present invention is not so limited in its application however, in so much as it may be used in maritime applications, where vessels dock against a wharf or pontoon, and where relative movement occurs between these.
- An object of the present disclosure therefore is to substantially ameliorate this difficulty, or to at least provide a fender assembly which is a useful alternative to the fender assemblies according to the abovementioned preceding disclosures.
- a fender assembly comprising an elongate support adapted to be attached to a surface of a support structure, the elongate support defining surfaces both inwardly and outwardly directed relative to the support surface, a resilient elongate fender mounted on the outwardly directed surface of the support and guided there along for vertical sliding movement relative thereto, and the inwardly directed surfaces defining a housing for a biased fender restraining means co-acting with and adapted to resist downwardly directed sliding movement of the resilient elongate fender relative to the elongate support.
- the resilient elongate fender is a solid rubber or rubber-like block.
- the elongate support is adapted to be attached to a surface of a support structure by way of its comprising an elongate planar or channel section plate which is fixable to the dock support surface by means of welding.
- the biased fender restraining means comprises a spring guide element upon which a spring is disposed and a transverse abutment extending from the spring guide element against which an underside of the resilient elongate fender engages when this is in a normal at rest position, and whereby any downwards movement of the resilient elongate fender causes simultaneous downward movement of the abutment and spring guide element, and thereby compression of the spring.
- the resilient elongate fender will slide upwards relative to the support under the influence of an external upwards force applied thereto and then return to its at rest position under its own weight when the force is removed.
- the spring guide element is a rigid element.
- the spring guide element is a rod.
- the spring guide element is a flexible element. In one form, the spring guide element is a length of cable.
- the spring guide element may be a flexible one, as its key load state is in tension, when the resilient fender is displaced downwardly against the bias of the spring.
- An advantage of a flexible element is that it cannot be plastically bent in the same way that a rigid elongate rod can. This is especially relevant when one considers that a bent rigid element of this type (i.e. a rigid rod bent by an impact there against) can render the fender assembly unserviceable.
- the outwardly directed surface of the elongate support defines an outwardly projecting vertical guide track.
- the outwardly projecting vertical guide track has inwardly directed surfaces defining a housing for the biased fender restraining means.
- the resilient elongate fender comprises a slotted keyway extending centrally along its rear face, said guide track slidably engaging within said keyway.
- the keyway extends between top and bottom faces of the resilient elongate fender and said guide track has a length which approximates the length of keyway, and wherein the abutment is located adjacent the lower end of the track.
- the outwardly directed surface of the elongate support defines a recessed vertical guide track
- the resilient elongate fender comprises a projection of matching shape extending from a back side thereof, so that this projection may slide down into the guide track and be slidably retained by this.
- inwardly directed surfaces of the elongate support define a pair of spaced apart housings, each of which houses a biased fender restraining means.
- each biased fender restraining means comprises a spring guide element upon which a spring is disposed, and a common transverse abutment extending between the two spring guide elements, against which an underside of the resilient elongate fender engages.
- the projection extends between top and bottom faces of the resilient elongate fender and said recessed guide track has a length which approximates the length of the projection, and wherein the abutment is located adjacent the lower end of the track.
- the elongate support is fabricated from elongate lengths of commercially available steel section.
- these commercially available steel sections include an elongate length of flat plate having first and second opposing major faces, two identical lengths of elongate angled section, each of these being welded along an edge thereof to the same major face of the flat plate so as to be extending in the same direction longitudinally, but also so as to be spaced apart, substantially parallel, and oppositely directed, so as to define between them, a passageway.
- these commercially available steel sections from which the fender assembly is fabricated comprises a length of steel channel, and a pair of lengths of elongate angled section, where each of a pair of parallel, spaced apart elongate edges of the channel has an inner surface of one of the angled sections welded thereto, such that these angled sections are parallel and spaced apart.
- the invention may be said to reside in a method of fabricating an elongate support for a fender assembly as described above, the method including the step of cutting elongate lengths of commercially available steel section to the same length, and then welding these together.
- the invention may be said to reside in a loading dock assembly incorporating a pair offender assemblies as claimed any one of the preceding claims to a fender assembly.

- Figure 13 is a front view of the elongate support in Figure 10;
- Figure 14 is a side view of the elongate support in Figure 10;
- Figure 15 is a rear view of the elongate support in Figure 10.
- Figure 16 is an underside view of the elongate support in Figure 10.
- the fender assembly 1 comprises an elongate steel support 2, which, in use, may be welded to a vertical support surface of a dock; a resilient elongate fender 4 in the form of solid rubber block (represented with dashed lines in Figure 1) mounted on the support 2 and guided there along for sliding movement relative thereto, and a biased (spring loaded) fender restraining mechanism 6 which supports the resilient elongate fender 4 so as to resist downwardly directed sliding movement of the fender 4 relative to the elongate support 2.
- the elongate support 2 is manufactured so as to have surfaces outwardly directed from the support surface of the dock, which define a generally 'T-shaped' guide track 8 for the resilient fender 4.
- the resilient fender 4 will have a groove of matching shape formed or moulded into a back side thereof, so that the resilient fender 4 may slide down onto the guide track 8 and be slidably retained by this.
- the outwardly projecting vertical guide track 8 has inwardly directed surfaces defining a housing (in the form of passageway 10) for the biased fender restraining means, so that at least the spring 12 and the rod 30 upon which the spring 12 is disposed may be housed.
- a housing in the form of passageway 10
- An advantage of housing the spring 12 and rod 30 in this fashion is that they are guarded and therefore less susceptible to damage, dirt and weathering; a further advantage is that the pinching hazard posed by the spring 12 is significantly reduced as compared with an exposed spring.
- the elongate support 2 is fabricated from commercially available steel sections. These commercially available steel sections include an elongate length of flat plate 20 having first and second opposing major faces, and two identical lengths of elongate angled section 22 and 24. Each of the lengths of angled section is welded along an edge thereof to the same major face of the flat plate so as to be extending in the same direction longitudinally, but also so as to be spaced apart, substantially parallel, and oppositely directed. Between them, these assembled steel sections define the passageway 10 in which at least the spring 12 and the rod 30 are housed.
- the upper corners of plate 20 are cut so as to be bevelled; these bevelled corners 20a and 20b are less susceptible to bending (than an unbevelled corner) when the elongate support 2 is in service as part of a fender assembly 1. Moreover, these bevelled corners 20a and 20b reduce the effort required to slide a resilient elongate fender 4 on to the 'T-shaped' guide track 8, of which this plate 20 forms a part. This is particularly useful when a worn or damaged resilient elongate fender 4 must be replaced
- the spring 12 is a relatively heavy duty helical compression spring, which is disposed upon a rod 30; this spring 12 is retained between a spring retention tab 32 that is welded to the upper end of the rod 30, and a spring supporting plate 34 which extends across the lower end of the passageway 10.
- the upper end of the passageway 10 is similarly closed off by the welding of a blank of steel plate 35 in the space defined between the length of flat plate 20 and the lengths of elongate angled section 22 and 24.
- this blank 35 has been outlined with dashed lines in Figures 3, 4 and 5. Closing off the upper end of the passageway 10 in this fashion prevents miscellaneous debris from entering the passageway 10 via this upper end, and potentially fouling operation of the spring 12 and rod 30.
- This spring supporting plate 34 has a hole 36 therethrough, through which the rod 30, but not the spring 12, may pass with a sliding action.
- a plate 40 Attached to the lower end of the rod is a plate 40 forming a transverse abutment which extends outwardly so that the lowermost edge of the resilient elongate fender 4 may abut against this.
- any movement of the trailer up or down will cause the resilient elongate fenders 4 offender assemblies 1 to move in the same way. While the resilient elongate fenders 4 may slide upward from the rest position without meeting resistance from the springs 12, any downward movement will meet resistance from the springs 12.
- this elongate support 200 is manufactured so as to have surfaces outwardly directed from the dock which are defining a generally 'C-shaped' recessed or concave guide track 202 for the resilient fender 204 (represented with dashed lines in Figure 2).
- the resilient fender 204 for this support 200 will have a projection of matching shape extending from a back side thereof, so that the resilient fender 204 may slide down into the guide track 202 and be slidably retained by this.
- the surfaces of the elongate support 200 which are directed inwardly toward the dock define a pair of spaced apart passageways 210 (housings) in which one each of the two springs 212 of the spring loaded fender restraining means may be housed.
- These two springs 212 are disposed upon a u-shaped rod 215 in a fashion similar to that disclosed above.
- a transverse portion of the rod 215 extends between parallel portions so as to fo ⁇ n thereby a transverse abutment; the lowermost edge of the resilient elongate fender 4 abuts against this transverse portion of the rod 215.
- the elongate support 200 is fabricated from commercially available steel sections. These commercially available steel sections include a length of steel channel 213, and a pair of lengths of elongate angled section 214 and 216. The elongate edges of the channel 213 each have an inner surface of one of the angled sections 214 and 216 welded thereto . These angled sections 214 and 216 are spaced apart, parallel and they slightly overlap the elongate edges of the channel 213. Otherwise, elongate support 200 operates in the same way and includes the same features as elongate support 2 described above.
